with Azygos Continuation. Upper: Frontal chest radiograph shows a soft tissue mass at the tracheobronchial angle with a smooth margin (white arrow). A tubular structure descends to the right of the spine (yellow arrows). The aorta is on the left. The lateral view does show a retrocardiac triangular density consistent with an IVC. Lower: Serial, contrast-enhanced CT scans of the chest and upper abdomen show an enlarged azygos vein (yellow arrow) that decsends to the right of the aorta. There is no intrahepatic IVC. The liver is midline (black arrow). There are multiple spleens present (polysplenia) (yellow circle).For these same photos without the arrows, clickhere and here
